Either during that section or after was the part where Matt called fake!Nathan about Past!Hero's amnesia and fake!Nathan told Matt to pressure Hiro for information on future plans (meaning the dedication in the show). And then fake!Nathan fetching Suresh in as a presidential advisor, telling him to go help Matt with Hiro, and getting Suresh to admit through a logic train that they must kill all the mutants since Suresh can't figure out how to "cure" them.

I think that's all the threads.

(P.S. Past!Peter is much cuter *biased*)
